Faulin Castle is a beautiful late 15th-century building situated opposite the Yonne Valley, at the foot of a hill in Lichères-sur-Yonne. It is a private property but can be visited by appointment, on selected dates and during the Heritage Days. In Gothic and Renaissance style, the elegant manor house has nevertheless retained its defensive identity with its dry moat and imposing rampart, as well as pieces of ordnance, bretèches, murder holes and arrowslits.
It is home to the Museum of Medieval Technical Innovation, created by an engineer with a fascination for history and mechanics. This educational attraction is organised in the form of themed workshops on medieval inventions in various fields (agriculture, astronomy, clock-making, printing, etc.). In addition to the information in the guide, which includes the background to the exhibits, the public can handle the objects and try their hand at some activities of yesteryear, such as dyeing wool or printing sheets.
